摘要
在分析铁路供电SCADA系统中E1环形远动通道的物理构成、逻辑拓扑的基础上,总结了点对点和环形2种通道的优缺点。根据通道和路由器的冗余特性,提出了变电站内通信设备的3种典型配置方案:双环单路由器、双环双路由器、单环单路由器。从设备造价、通信可靠性、实施和维护3个方面对3种方案进行了对比分析,发现单环单路由器方案简单实用,造价低,获得了最广泛的应用。最后实现了单环单路由器方案应用于京沪线的配置。
The physical layers and logical topology of El ring communication channels are analyzed,and the advantages and disadvantages of peer-to-peer channel and ring channel are summarized. According to the redundancy characteristics of channel and router,three typical configuration schemes of communication devices in a substation are proposed ： dual-ring single-router, dual-ring dual-router and single-ring single-router,which are compared in equipment cost,communication reliability,implementation and maintenance. The single-ring single-router scheme is simple,practical,inexpensive and widely used. The single-ring single-router scheme configured for Beijing-Shanghai railroad communication channel is presented.
